If you are going to gig, then I recommend a nice rack-mounted wireless such as Audio-Technica or Sure. Back in the late 90's, Guitar Center used to have a special contract with Audio-Technica, and could sell their "DR" series at a low cost. These units were very solid and worked well. Of course, these days, I suspect VHF wireless are becoming less popular and UHF is the way to go.
All of this is overkill, though. Bedroom? Get the cheapest wireless you can find and enjoy ripping it up while jumping on your bed! :)
